Patent experimental use - ineffectiveness of Lough V Brunswick (Fed Cir 1997)

Preface

Please imagine you are a mechanic of the car. Engine coolant may corrode a part of the motor frequently. The mechanic needs to replace this part once a year. To deal with this problem, design a new part containing the coolant. Hopefully the part you made will last long.

In order to know whether the part will work, you decide to test the invention. You will install parts to your friends Explain that you want to know whether the parts will help protect the motor from corrosion. Your friend will use the car for two years, but there is no problem. Therefore, your invention is superior to existing products. You have decided to patent your invention.

Later, some car makers will start selling new automotive motors where your parts are attached to the car. Believe that the company has used your patented invention illegally, you will appeal to enforce your patent. However, before the opportunity to present evidence, the car manufacturer asks the court to file your suit. In the summary judgment motion, the automaker insists that trial is unnecessary, even if everything you say is correct, since it does not violate the patent code. As opposed to patent law, automobile manufacturers have claimed that they have maintained your patent rights since they have spent more than a year publishing your invention. In other words, automobile manufacturers claim that the Patent and Trademark Office should never grant you patents.

But you think you need two years to test your invention to ensure that the device works as you intended. You inform the judge that the jury must decide whether to prevent the patent of the invention through long-term inspection. You think that testing the device for a long time in the public and invalidating your patent is not a question the judge can decide without hearing the evidence of the problem.

But the judge has contracted with the car manufacturer that this is a legal issue. This sentence means that the judge will decide the question without hearing the evidence. In spite of your opposition, the judge recognizes the movement of the automaker for summary judgment. This means that the judge arbitrated the problem of the law without hearing your evidence, so it did not get the opportunity to undergo the jury trial.

This scenario can happen in reality. Like a fictional court, Lough v. The Federal Circuit Court of Appeals for Brunswick Corp. examined whether the inventor tested the invention whether it is a matter of facts or a matter of law. The Rough Court insisted that it was a matter of law to decide the use of the invention in the examination. The Lough Court's decision was not able to get rid of the confusion of deadlines for applying for patents. Fortunately, the US Supreme Court ruled that Pfaff v. We are planning to consider the deadline of the patent code of Wells Electronics's patent application at once. Hopefully the Supreme Court will settle this area of patent law.

This note shows some of the Lough Court mistakes that have created the current mess of patent application deadlines. This note begins with explaining the patent system of the United States, including that the inventor uses the invention before filing the patent. The second part is the Supreme Court's Kendall v. Regarding holding Winsor, we consider these issues to be a matter of fact before using the invention before it is patented. Part III shows how the Federal Circuit overlooked this Supreme Court precedent. In Part IV, Lough v. Brunswick Corp. I will explain the facts, procedures, possession and inference. Part V analyzes the Lough judgment of the Federal Circuit Court of Appeals. Specifically, in Part 5, the Federal Circuit Court of Appeals deviated from the law of the Supreme Court precedent, if the court claimed that the prohibition of using the invention before the patent was a legal matter He insists. Also, the Federal Circuit made a series of errors up to Lough. This note concludes that the Federal Circuit misunderstands the case law and states whether the inventor tested the invention should be a matter of fact or not.

I. State of law

A. General patent law

Under certain conditions, the patent code gives the inventor its own exclusive right. When the inventor acquires a patent, the patent code grants exclusive rights to the inventor for 20 years after patent application. During this time, the patent owner has the exclusive right to manufacture, sell, import or use the invention in the United States.

In order to avoid unduly prolonging these exclusivity rights, inventors have limited time to apply for patents to protect the invention. The reference point for this deadline is the date on which the inventor filed a patent. The patent system provides a one-year grace period during which the inventor can use the invention before filing a patent.

B. Public use

If the inventor disclosed the invention more than a year ago before filing the invention, the inventor loses the right to obtain the patent. If the inventor does not file a patent within a year after using the invention to the public, the inventor does not wish to protect the patent and the inventor claims that the invention has been donated generally to the inventor. As a result, the inventor can not obtain a patent one year after use in the public.

When someone uses the invention in the intended way, it is called "public use". The general use of the invention should not be generally accessible. For example, if you have a non-intrusive navigation device of an inventor aboard an airline's domestic commercial aircraft on an airplane, that device is commonly used. The public use doctrine is codified in patent code 102 (b). Article 102 (b) of the Patent Act prohibits inventors from obtaining a patent if the inventor disclosed the invention more than a year ago prior to the application of the invention.

C. Experimental use

When the inventor examines the invention, the court extends the period of one year. Section 102 (b) does not explicitly consider the need for the inventor to test the invention. Instead, "experimental use" is a carefully created doctrine intended to give the inventor extra time to improve the invention. In the meantime, the inventor can perform experiments in general without losing the protection of the patent code. The patent law determines that experimental use will be done when the inventor or someone else tests the invention in such a way. Experimental use of the invention may deny the claim of 102 (b), which claims that the patent is invalid. This gives the inventor a period of public use and a reasonable period of experimental use to the inventor before prohibiting inventors from obtaining a patent.

II. Supreme Court Public use and experimental use are de facto questions

In deciding the issue of public use and experimental use, the Supreme Court treats bar 102 (b) as a de facto problem uniformly. The jury usually determines the de facto problem. In Kendall v. Winsor, the Supreme Court insisted that the judge should decide whether legal evidence causing a loss of patent rights is adequate.

In Kendall, inventors used workers to help test and develop textile machinery. Before completing the invention, one employee left the business of the inventor and built a similar machine of the textile company. The question of the examination judge was whether the inventor invalidated the patent using the experimental apparatus before filing the patent. The jury discovered that the patent of the inventor was experimental and denied the claim of official use of the defendant, so the patent is effective.

A defense appeared. The Supreme Court held that the public use and experimental use are fact matter and Kendall was experimenting with the invention before applying for a patent, so the law backed the jury's validation of the complaint. The Supreme Court noted that only the jury can properly assess the many facts necessary to determine experimental use. This fact was argued to the Supreme Court that only the jury could judge whether the inventor proved that experimental use denied allegations of public use. Therefore, the Supreme Court tacitly asserted that experimental use is a matter of fact, as the jury can only determine the actual question.

III. Federal cruiser from Kendall

The Federal Circuit Court of Appeals adopted a different approach to the Kendall Court as to whether experimental use is a fact or a matter of law. Over time, the Federal Circuit Court of Appeals determined three cases that ultimately conclude that experimental use is a matter of law. In this section we will explain these three cases to show the way to the withdrawal of the Federal Circuit Court of Appeals.

The Federal Circuit Court's law on whether experimental use is a fact matter or a matter of law is not entirely consistent. The Federal Circuit Court of Appeals sometimes claims that experimental use is a matter of fact. The Federal Circuit Court of Appeals insists that experimental use is a legal matter. Typically, the Federal Circuit Court of Appeals does not provide allowances for selecting one rather than others. The chain of inconsistencies began in one case of the Federal Circuit.

A. In Reforestar

In Foster, the Patent Office Court of Appeal ("Board of Directors") rejected the appeal of patent refusal. The Council rejected the appeal as the invention was too obvious to justify the patent. After the applicant appeared, the US Court and the Court of Appeals, the predecessors of the Federal Circuit Court of Appeals, confirmed the Board's patent refusal. The only problem before the court was whether the present invention, which is a synthetic rubber material, was an improvement under the age of 103. Section 103 prohibits patents for obvious improvements to those familiar with the appropriate field. Therefore, if Foster's rubber material is obviously improved, it is forbidden to be under the age of 103 from the subject of patent protection. Foster Court claimed that synthetic rubber is just a slight improvement. Foster does not state whether the 102 (b) bar is a fact matter problem or a law problem.

B. at cocoran

The customs court and the patent appeals court relied on Foster to decide at Cocoran. Corcoran was a Board Rejection appeal of a patent on a problem separate from that of Foster. Corcoran contained a total of 102 (b) / 103 bar. The Council claimed that the inventor's athlete sold Corcoran's device purely obviously improved devices. This problem was acknowledged anywhere that the board condemned the patent as Corcoran combined the one-year deadline 102 (b) with 103 bar. The present invention was a plastic sheet for window blinds. If Corcoran's plastic sheet component is obviously improved, 103 prohibits obtaining the patent of the present invention. Corcoran's court confirmed the Board's patent refusal as a similar plastic sheet was sold and Corcoran's invention was only a legal obvious improvement. The Corcoran Court is based on the decisions of the law referred to Foster.

The Cocoran Court relied on Foster Holding and judged that the problem of public use and obviousness is a legal issue. However, Foster did not link this public use problem to obviousness. Its ownership is completely related to a separate problem - whether obviousness is a legal problem or not.

Both Corcoran and Foster were not purely experimental use cases. When faced with a purely experimental use case, the Federal Circuit Court decided that all 102 (b) bars are legal issues, using the Foster reading of the Corcoran Court. This mistake was made by the Federal Circuit once again by Barmag Barmer Maschinenfabrik AG v. It became prominent when I misunderstood the law of Murata Machinery, Ltd.

C. Barmag Barmer Maschinenfabrik AG v. Murata Machinery, Ltd. About enterprise | Contacts

At Barmag, machine manufacturers complained of patent infringement competitors. Both parties rejected whether the thread handling machine was experimentally used. The district court adjudged patent invalidation as a matter of law. After Barmag appeared, the Federal Circuit found that Barmag invalidated the patent because Barmag violated the bar at 102 (b). According to the Federal Circuit Court, all 102 bar, including public use, is a legal matter. Bermag did not refer to Kendall, but the Supreme Court precedent that the experimental use turned out is indeed a question. Instead, the Barmag Court is based on In re Corcoran's interpretation. However, Corcoran did not handle all 102 (b) bars. Is Corcoran totally related to another problem? Whether the problem of public use and obviousness is a matter of law or fact. The Federal Circuit Court of Appeals, Lough v. He relied on three misleading analyzes that Brunswick Corp. decided.

IV. Rough V. Brownwick

Lough v. Brunswick Corp. was a patent infringement dispute involving ship parts. The jury found that the case infringed the plaintiff's patent. In the appeal, the Federal Circuit Court of Appeals reverses whether the experimental use denies public use whether it is a legal matter properly secured by the judge to decide,

A. Facts

Steven G. Lough, who served as a boat dealer in Sarasota, Florida in 1986, Lough cooperated with the Brunswick inboard / outboard motor as part of his work. While repairing these motors, he noticed that certain seals often corrode from contact with seawater.

Lough designed a new seal to prevent this corrosion. After making six prototypes, he attached the seal to the boat and friend's seal. boat. The test insists that Lough tested using a prototype. For over a year, Rough did not ask anyone if the seal went well.

Lough did not patent his invention during this time. Instead it took more than two years to find out if the seal was adequate. According to his test results, the rough seal was superior to any other seal at the time. Lough filed a patent in June 1988 and the Patent and Trademark Office issued a patent one year later.

Mr. Lough then filed a patent infringement lawsuit against Brunswick and sent a jury verdict. This problem became a problem everywhere where Lough places the section in a friend and tests it. The boat was a public use. The jury found that Brunswick did not prove that Lough 's invention was published one year before the patent application date. The trial court denied the inevitable movement for Brunswick 's legal judgment. Mr. Brunswick claimed that the jury verdict was wrong because the official use of invention occurred more than a year ago before Lough applied for a patent.

B. Federal Circuit Court decision

At the appellate trial, the jury examined whether the use of Lough's prototype was appropriately determined to be experimental in 1986. The court held that the invention was a legal matter if the invention was used for official use for more than a year before filing a patent under paragraph 102 (b). The Federal Circuit held this by Manville Sales Corp. v. It was assigned to Paramount Systems, Inc. In Manville, the Federal Circuit Court of Appeals said experimental use is a legal matter. However, the Manville Court did not state the authority of this excuse.

Lough's court discovered that the six prototypes of Lough are actually published. The court has determined that Lough has offered prototype seals to general members for unlimited use at no charge. The Lough Court concluded that the discovery of the experimental use of the jury is erroneous as a legal matter.

V. Analysis

The rough court mistook its judgment. The court did not follow the Supreme Court precedent. Inadvertently, experimental use was erroneously appealing as a matter of law due to chain of errors. The court of Lough should have followed Kendall and claimed that experimental use is a matter of fact. Instead, the Federal Circuit pursued a series of mistakes in order to discover that experimental use is a legal issue.

A. Rough Court incorrectly chose not to comply with the Supreme Court's Kendall judgment

The US Supreme Court insisted that experimental use was a matter of Kendall's facts. Despite this binding precedent, the Lough Court insists that public use is a legal issue, conflicting that making a mistake in its experimental use is a legal matter . The Supreme Court has already decided an appropriate analysis of the dispute between public use and experimental use. The Supreme Court has dealt with public use and experimental use uniformly as a de facto problem. The need for consistency in US patent law is an attractive reason to follow Kendall's remarks which holds that public use and experimental use are de facto problems.

In order to maintain consistency, the Supreme Court instructed the court to postpone to the trial court. Findings of facts in case of judgment including 102 (b) bar. The Supreme Court has never treated legal problems as legal issues. The Supreme Court precedents provided guidance on experimental use before the Federal Circuit Court of Appeals.

B. Foster-Corcoran-Barmag Federal Circuit Court of Appeals when reading Trio

The Federal Circuit Court of Appeals misunderstood as a precedent for experimental use. Bermag's mistake was the cornerstone of a series of mistakes. In Bermag, the Federal Circuit affirmed that 102 (b) bar is a matter of law. Barmag did not point to Kendall which proved experimental use is a de facto problem. The Barmag Court's ruling was based on In er Corcoran's erroneous reading that the Barmag Court claims that 102 (b) bar is a legal matter.

However, Re Corcoran combined the 102 (b) / 103 question and used the label "law problem". In other words, the In re Corcoran Court never said that purely the issue of 102 (b) is a legal matter. Instead, the court cited In re Foster on the proposal that whether 102 (b) bar exists is a legal matter.

Foster does not stand on this proposal. The bar in section 102 (b) was not an issue in Foster, either. The only problem of the court was whether the invention was an obvious improvement. If it is a clear improvement it will not be subject to patent protection under the age of 103, not 102. Barmag's weak holdings replied from errors stacking on error.

C. The confusion of the Federal Circuit appeared confusing

The confusion at the Federation Circuit's Foster-Corcoran-Barmag trio was more confusing. The Barmag court misunderstood that the court made an appeal to reexamine the experimental use using Corcoran and Foster. These cases do not address whether the 102 (b) bar is a legal problem or a factual question. Without noticing this error chain, Lough's court made a remarkably similar mistake by supporting the suspension of experimental use with unsupported authority.

Lough affirmed that it is a matter of law as an authority to possess experimental use in Manville. Manville unconsciously mentioned this proposal without quoting any authority. As was done in the trio of Foster-Corcoran-Barmag, the Federal Circuit reiterated mistakes again at the time of error by reading cases from the context. This mistake that was rejected at the rough court holding the use of this experiment by mistake is a legal matter. In addition, the wrong interpretation of the Foster-Corcoran-Barmag trio and Manville circuitry requires reevaluation of the Supreme Court's ruling of experimental usage to restore sense to the 102 (b) bar.

D. Why Experimental Use should be a fact

The Supreme Court should reevaluate experimental usage by analyzing why experimental use should be a matter of fact. The Supreme Court should review Kendall's possession that the jury should decide the question of experimental use. If a jury decides empirical use under the guidance of a judge, that exercise will bring consistency in the decision of experimental use. In Kendall, the court did not reject the jury. Because an unrestricted review of many conflicting facts can lead to inconsistent judgment. If the examination by the Federal Circuit is unlimited, the Circuit Court, like the Foster-Cocoran-Bermag trio, may choose different facts and produce inconsistent results.

Also, if the Federal Circuit Court of Appeals can freely review the jury results of experimental use, appeals to the Federal Circuit Court of Appeals will increase. The Court of Appeals should ensure that those who do not agree with the jury's verdict should not open the floodgates and minimize the burden of the incident. In keeping the jury's findings on experimental use not obviously wrong, the Federal Circuit Prevents wasting resources of the lower courts used for the first time to determine experimental use . Limiting the review of the jury's experimental usage decision can also minimize the excessive use of the Federal Circuit's resources.

However, the rough court claimed to apply experimental use as a mistake as a matter of fact. The Rough Court explained that the sentence is unpredictable. Lough's court commented that the Court of Appeal Court's ruling is often missing provides consistency.

In fact, consistency may be higher if the judge determines the problem of experimental use. In different cases with similar facts, different jurors may make different judgments. If judges, patent attorneys, and business people can predict the validity of a patent, there is not much appeal for experimental use. As a result, Lough Court insisted that judges should decide the problem of experimental use.

However, the Supreme Court appropriately considered and refuted these concerns in Kendall. Congress created a patent system that would generally benefit by providing temporary remuneration to the inventor in exchange for the public release of technical progress. Excessive obedience to patent challengers can disrupt the negotiations between inventors and the public. Because of the flaw in the jury system, the best way to decide experimental use is to have multiple judges checked by an experienced judge.

The previous case includes inventor's exercise and trial fact finding procedure. The de novo review of verdict of experimental use is difficult and severe. Examination courts should not be able to benefit from the proceedings, so experimental and official use should be de facto questions as frequent conflicting judicial evidence requires finding reliability.

Conclusion

In Rough versus Brunswick, the Federal Circuit Court of Appeals erroneously determined that experimental use was a legal matter. The Lough Court ignored the Supreme Court's Kendall case and misinterpreted other precedents. Ignored case law provides better reasoning and guidance for the use of doctrines of experimental use. Immediately the Supreme Court, Pfaff v. We will have the opportunity to adopt the criteria for experimental use in dominating Wells Electronics. The factual judge should decide whether the inventor used the invention before the inventor used the patent component experimentally, whether the judge or the jury.
